Morphology

Anapsida = anapsid (opaque) = an + apsid + a

The formation from 'anapsid' + '-a' is a technical taxonomic nominalization and is not inferable by an average B1 learner from the components.

Etymology

Anapsida comes from Greek parts a- meaning 'without' and -apsida meaning 'arch' or 'opening', so the name literally points to being 'without openings'. That's why scientists use it for reptiles like turtles whose skulls have no side holes.
